Before you choose

Check the release date

Release dates run from 2026-09-23 to 2026-03-15 in the listed records. A later date can help you focus on newer entries when comparing names.

Read the family label

Most entries use the z-ai family label. GLM Flash Latest and GLM Latest use the ~z-ai family label, so check that field when sorting or filtering models.

Separate batch variants

GLM 5.3 Flash (batch) and GLM 5.3 (batch) have separate official pages from their namesake models. Treat the batch label as part of the model name when choosing a page.

Open the model page

The listed official pages are on OpenRouter and use the Z.ai model path. Open the page tied to the exact model name before reviewing its details.
